[0019] The following will be combined with the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0020] This embodiment provides a water well wall cleaning system, which will be referred to as the cleaning system in the following text. Figures 1 to 3 As shown, it includes a base 100, a guide part 200 and a cleaning part 300. Among them, the guide part 200 includes a plurality of guide units 210 arranged at intervals along the circumference of the base 100. Each guide unit 210 includes a sliding member 211, two mounting rods 212 and a guide wheel 213. The sliding member 211 is movably arranged on the base 100, one of the two mounting rods 212 is hinged to the base 100, the other of the two mounting rods 212 is hinged to the sliding member 211, and the free ends of the two mounting rods 212 are respectively hinged to the guide wheels 213.

[0021] The cleaning part 300 includes a plurality of cleaning units arranged at intervals along the circumference of the base 100, each cleaning unit includes a swing arm 310, and a water nozzle 320 arranged on the swing arm 310 and connected to a water supply device arranged on the base, each water nozzle 320 can expand outward or retract inward as the swing arm 310 rotates.

[0022] Based on the above overall structure, the cleaning system of this embodiment can adjust the distance between the guide wheel 213 and the axis of the base 100 by adjusting the position of the sliding member 211, so that the cleaning system can be applied to the cleaning of the well wall of water wells with different calibers. By adjusting the extension degree of each water nozzle 320, each water nozzle 320 can be as close to the well wall as possible for water wells with different calibers, so as to have a better flushing effect on the well wall. Specifically, when the cleaning system of this embodiment is used, the position of each guide wheel 213 and each water nozzle 320 can be adjusted in advance outside the well according to the caliber of the water well, so that it is compatible with the diameter of the water well, and then the cleaning system can be hoisted into the well, and each guide wheel 213 guides the downward movement of the base 100, and each water nozzle 320 flushes the debris attached to the well wall.

[0023] For specific structure, refer to Figure 1 and Figure 4 As shown, the base 100 of this embodiment is provided with a first barrel section 110, and a cavity 101 is provided in the first barrel section 110. A water inlet pipe 111 extending into the cavity 101 is provided at the bottom end of the first barrel section 110, and the water inlet pipe 111 is connected to the above-mentioned water supply device. A water outlet pipe 112 is provided at the top end of the first barrel section 110, and the water outlet pipe 112 is connected to each water nozzle. A filter screen 113 is also fixed in the cavity 101, and the filter screen 113 covers the intersection where the inner hole of the water outlet pipe 112 intersects with the inner wall of the cavity 101.

[0024] refer to Figure 1 As shown, the base 100 of this embodiment also includes a second barrel section 120 fixedly connected to the first barrel section 110 and located below the first barrel section 110. The above-mentioned water supply device is a water pump fixedly installed in the second barrel section 120. A first filter hole is provided on the side wall of the second barrel section 120, so that the water in the well can enter the inner cavity of the second barrel section 120 through each first filter hole, so as to be sucked by the water pump and pumped into the above-mentioned water inlet pipe 111. Among them, the connection method between the output end of the water pump and the water inlet pipe 111 can refer to the prior art, and will not be repeated here. It should be noted that the water pump is not shown in the drawings of this embodiment because it does not affect the understanding.

[0025] In this embodiment, reference Figure 4 As shown, a filter plate 114 is fixedly provided in the cavity 101, which is located above the water inlet pipe 111 and below the filter screen 113. A cover ring 115 is fixedly provided on the lower end surface of the filter plate 114. The cover ring 115 includes a conical section 1151 and a cylindrical section 1152 connected in series. From top to bottom, the diameter of the conical section 1151 gradually increases, and the top end surface of the cylindrical section 1152 is connected to the bottom end surface of the conical section 1151. The water inlet pipe 111 extends into the cover ring 115, and the top end surface of the water inlet pipe 111 is higher than the top end surface of the cylindrical section 1152.

[0026] By providing the above-mentioned filter plate 114 and cover ring 115, the water entering the cavity 101 through the water inlet pipe 111 will first move downward, and then enter the top of the filter plate 114 from the gap between the cover ring 115 and the inner wall of the cavity 101. In this process, the solid particles 116 in the water will fall on the bottom surface of the cavity 101 due to their greater density than water, and thus be collected.

[0027] refer to Figure 1 and Figure 2 As shown, in this embodiment, a guide shaft 220 is provided on the base 100, and an external thread is constructed on the outer periphery of the guide shaft 220, and two limit plates 230 are screwed on the external thread, and the above-mentioned sliding member 211 is specifically sleeved on the guide shaft 220 and located between the two limit plates 230, and a first elastic member 240 is respectively provided between the two limit plates 230 and the sliding member 211.

[0028] In this embodiment, by setting the above sliding member 211, the positions of the two limiting plates 230 can be adjusted along the axial direction of the guide shaft 220 by rotating the two limiting plates 230, so as to adjust the position of the sliding member 211, so that the guide wheel 213 can move outward or inward. Specifically, by moving the two limiting plates 230 and the sliding member 211 downward, each guide wheel 213 can be moved outward; and by moving the two limiting plates 230 and the sliding member 211 upward, each guide wheel 213 can be moved inward. By setting the first elastic member 240 between the two limiting plates 230 and the sliding member 211, the cleaning system can have better passability. When the diameter of the well wall is reduced or there are attachments on the well wall, the position of the guide wheel 213 can be automatically adjusted by compressing the first elastic member 240 by the sliding member 211, so that the cleaning system can continue to move.

[0029] In this embodiment, the first elastic member 240 is a spring that is sleeved on the guide shaft 220 and abuts between the sliding member 211 and the corresponding limiting plate 230 .

[0030] It should be noted that the hinged structures between each mounting rod 212 and the sliding member 211 , the hinged structures between each mounting rod 212 and the base 100 , and the hinged structures between the mounting rod 212 and the guide wheel 213 may refer to the prior art and will not be described in detail herein.

[0031] In this embodiment, reference Figure 1As shown, a sample collecting chamber 400 is provided at the bottom end of the base 100, and the sample collecting chamber 400 includes a bottom plate 410 fixedly provided on the base 100, and an inverted cone-shaped ring body 420, the bottom end of the ring body 420 is fixedly connected to the bottom plate 410. In this embodiment, by providing the sample collecting chamber 400, the following scraping unit 500 can be used to collect scaling samples, so that the causes of scaling formation can be understood by sampling and analyzing the samples.

[0032] refer to Figure 1 and Figure 3 As shown, corresponding to each cleaning unit, a mounting plate 130 is fixedly provided on the base 100, and a rotating shaft is provided on the mounting plate 130, and the swing arm 310 is rotatably sleeved on the rotating shaft. The swing arm 310 includes a long arm section 312 and a short arm section 311 that are fixedly connected and not colinear, and the water spray head 320 is fixedly provided on the long arm section 312. An arc-shaped long strip hole 102 is constructed on the mounting plate 130, and a through hole is provided on the short arm section 311. The bolt 313 can pass through the through hole and the long strip hole 102 and be screwed with a nut, thereby constituting the fixing of the swing arm 310 relative to the mounting plate 130, and the position of the bolt 313 in the long strip hole 102 can be adjusted along the length direction of the long strip hole 102, so that the position of the water spray head 320 can be adjusted around the rotating shaft along with the long arm section 312. It should be noted that each water nozzle 320 is connected to the water outlet pipe 112 through a hose so as to maintain communication with the water outlet pipe 112 when the water nozzle 320 is adjusted around the rotation axis. Since it does not affect understanding, the hose is not shown in the drawings of this embodiment.

[0033] That is to say, by adjusting the position of the bolt 313 in the long hole 102, the short arm section 311 and the long arm section 312 can be rotated around the rotating axis respectively, so that each water nozzle 320 is moved away from or close to the axis of the base 100, that is, each water nozzle 320 is expanded outward or retracted inward, so that each water nozzle 320 is suitable for water wells of different calibers.

[0034] refer to Figure 1 and Figures 5 to 8 As shown, the cleaning system of this embodiment further includes a scraping unit 500 fixedly mounted on the base 100, and the scraping unit 500 includes a motor 510 mounted on the base 100, and a cleaning disc 520 that can be driven to rotate by the motor 510, and a plurality of scrapers 530 are arranged on the cleaning disc 520, and the scrapers 530 can scrape off the hard scale on the well wall as the cleaning disc 520 rotates. In this embodiment, by providing the scraping unit 500, the hard attachments on the well wall can be scraped off well, and the aforementioned water nozzle 320 can better wash the soft attachments on the well wall, and by combining the scraping unit 500 and each water nozzle 320, the well wall can be better cleaned.

[0035] In order to enable the scraping unit 500 to cope with changes in the diameter of the water well, specifically, the thickness of the scale on the well wall is uneven, and for excessively thick scale, multiple scrapings may be required. In this embodiment, each scraper 530 can slide on the cleaning disk 520 along the radial direction of the cleaning disk 520, so that the scraper 530 extends to different lengths by sliding on the cleaning disk 520, so that the scraping unit 500 can adapt to changes in the diameter of the water well.

[0036] For specific structure, refer to Figure 5 As shown, a mounting cavity 501 is provided in the cleaning disc 520, and three guide rails 521 extending along the radial direction of the cleaning disc 520 are provided on the bottom surface of the mounting cavity 501. There are three scrapers 530 that can slide on the guide rails 521 in a one-to-one correspondence. It should be noted that the number of the guide rails 521 and the scrapers 530 can also be two, four or other numbers.

[0037] refer to Figure 5 As shown, a first one-way clutch 540 and a second one-way clutch 550 are sleeved on the motor shaft 510 of the motor 510 for driving the cleaning disc 520 to rotate, and the installation directions of the first one-way clutch 540 and the second one-way clutch 550 are opposite. It should be noted that the first one-way clutch 540 and the second one-way clutch 550 can also be sleeved on a shaft driven by the motor shaft 510. The first one-way clutch 540 and the second one-way clutch 550 can both adopt existing products, and their structures and working principles are not described in detail here.

[0038] In this embodiment, reference Figure 5 As shown, the cleaning disc 520 is fixedly mounted on the first one-way clutch 540, and a first gear 551 is mounted on the second one-way clutch 550, and a transmission unit is provided between the first gear 551 and each scraper 530. When the motor 510 shaft rotates in one direction, the cleaning disc 520 can be driven to rotate via the first one-way clutch 540, and when the motor 510 shaft rotates in the opposite direction, the first gear 551 can be driven to rotate via the second one-way clutch 550, and each scraper 530 can be driven to slide along the radial direction of the cleaning disc 520 via the transmission unit.

[0039] Based on the above structure, in the cleaning system of this embodiment, the motor 510 shaft can drive each scraper 530 to slide along the radial direction of the cleaning disk 520 to adapt to the change of the diameter of the water well. After the position of the scraper 530 is adjusted, the motor 510 shaft can rotate in the opposite direction to drive the cleaning disk 520 to rotate and complete the cleaning of the water well wall.

[0040] refer to Figure 5 and Figure 6As shown, the transmission unit of this embodiment includes a driving disk 560 rotatably arranged on the cleaning disk 520, and a plurality of driving grooves 502 connected end to end are provided on the end surface of the driving disk 560, and the distance between each point on the center line of each driving groove 502 and the center of the driving disk 560 changes continuously, and each scraper 530 is provided with a thrust rod which can be inserted into each driving groove 502 one by one and can slide in the driving groove 502.

[0041] In this embodiment, by setting the above-mentioned driving disk 560, when the driving disk 560 rotates, the thrust rod will slide in the driving groove 502. Since the distance between the driving groove 502 and the center of the cleaning disk 520 is variable, the distance between the thrust rod and the center of the cleaning disk 520 is also variable, that is, the rotation of the driving disk 560 can enable each scraper 530 to slide synchronously along the radial direction of the cleaning disk 520.

[0042] refer to Figure 5 As shown, the transmission unit of this embodiment further includes a second gear 552 rotatably disposed on the cleaning disc 520 and meshing with the first gear 551, a third gear 553 coaxially connected to and fixedly connected with the second gear 552 and located in the mounting cavity 501, and a fourth gear 554 coaxially connected to the driving disc 560 and meshing with the third gear 553. When the shaft of the motor 510 drives the first gear 551 to rotate, the fourth gear 554 and the driving disc 560 can be driven to rotate through the second gear 552 and the third gear 553.

[0043] In this embodiment, reference Figure 5 As shown, a connecting shaft 555 for connecting the second gear 552 and the third gear 553 is provided between the second gear 552 and the third gear 553, and a damping pad is provided between the connecting shaft 555 and the cleaning disc 520, and the damping pad applies a damping force to the rotation of the connecting shaft 555. In this embodiment, by providing the damping pad, it is possible to avoid unexpected rotation of the driving disc 560. Specifically, after the motor 510 shaft drives the driving disc 560 to rotate in place, when the motor 510 shaft rotates in the opposite direction to drive the cleaning disc 520 to rotate, if the above-mentioned damping pad is not provided, the driving disc 560 may rotate, causing the scraper 530 to lose its position. By providing the damping pad, resistance can be applied to the rotation of the driving disc 560, thereby ensuring the position of the driving disc 560. It should be noted that the damping pad is not shown in the drawings of this embodiment because it does not affect understanding.

[0044] refer to Figure 7 and Figure 8As shown, in this embodiment, three friction blocks 561 are slidably provided on the top wall of the installation cavity 501, and each friction block 561 is evenly and spacedly arranged around the axis of the cleaning disk 520. A first wedge-shaped surface is provided on the top wall of the installation cavity 501, and a second wedge-shaped surface is provided on the friction block 561. When the friction block 561 slides in a direction away from the center of the cleaning disk 520, the first wedge-shaped surface can push the second wedge-shaped surface, so that the friction block 561 abuts against the driving disk 560.

[0045] When the cleaning disc 520 rotates to clean the well wall of the water well, the friction block 561 will be moved away from the center of the cleaning disc 520 due to the centrifugal force, and the friction block 561 will abut against the driving disc 560 through the pushing of the first wedge surface to the second wedge surface, so as to apply friction to the driving disc 560. Without the friction block 561, when the cleaning disc 520 rotates, the scraper 530 will be pushed by the well wall and act on the driving disc 560, which may overcome the above-mentioned damping force and cause the cleaning disc 520 to rotate. By providing the friction block 561, when the cleaning disc 520 rotates, the friction block 561 can apply friction to the driving disc 560, thereby preventing the driving disc 560 from moving unexpectedly.

[0046] In this embodiment, reference Figure 7 and Figure 8 As shown, a second elastic member 562 is provided between the friction block 561 and the side wall of the mounting cavity 501, and the second elastic member 562 applies a thrust to the friction block 561 to make the friction block 561 approach the center of the cleaning disk 520. By providing the second elastic member 562, after the cleaning disk 520 stops rotating, the second elastic member 562 can push the friction block 561 to reset, so that the driving disk 560 can be rotated again to adjust the position of each scraper 530.

[0047] The water well wall cleaning system of this embodiment further includes a camera unit disposed on the base 100 for capturing images inside the water well. The water well wall cleaning system of this embodiment further includes a control system for being placed outside the water well, the control system including a display screen for displaying images captured by the camera unit. The staff can perform corresponding operations on the cleaning system according to the images displayed on the display screen, for example, the staff can control the cleaning system to move up or down according to the cleaning effect of the well wall displayed on the display screen.

[0048] In this embodiment, a flow sensor, a flow velocity sensor and a flow direction sensor are also provided on the substrate 100. When the water well wall cleaning system is not cleaning the well wall, it is stationary in the water well. At this time, the flow sensor, flow velocity sensor and flow direction sensor provided on the substrate can monitor the flow rate, flow velocity and flow direction of the liquid in the water well for scientific research. It should be noted that the flow sensor and the flow velocity sensor can adopt existing products, and their structure and working principle will not be described in detail here. And since it does not affect the understanding, the flow sensor and the flow velocity sensor are not shown in the drawings of this embodiment.

[0049] The above are only preferred embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
